Question

A 24 volt battery of internal resistance 4ohm is connected to a variable resistor. At what value of the current drawn from the battery is the rate of heat produced in the resistor is maximum?
a)6A
b)2A
c)3A
d)4A

Answer 1

v = 24

Resistance=4ohm

V=IR

24=I×4

24/4=I

therefore,I=6A

hence, the current is 6 ampere
